I don't know whether Lint is OK,as described above I modified the arcanist source code in order to be able to commit this, I have no working linters.Otherwise it would always invoke lint without prompt which fails on windows as it tries to build the xhpast linter with the visual c++ by using make commands from the unix world which is totally wrong. But the first time I tried to commit this arcanist prompted me to explain why the linting failed so this could be committed without a successfull lint,afaik I aborted and the next times it would just refuse to commit(Exception:xhpast is broken),which is odd.Deleting arcanist and phutil and redoing the changes by hand again didn'T solve it,so it seems to save settings somewhere in the system, I have no clue where, %programdata%/phabricator doesn'T exist and .arcrc has nothing to do with that.

There's some unnecessary whitespace that should probably be cleaned up - most of the empty lines could probably be removed, and take a look at the bullet points here:

There should probably also be a unit test that verifies the regex works properly on expected output of mode con to prevent future regressions (possibly test English along with another language).

I'm not sure how to fix xhpast on windows -- I ran into similar issue previously when modifying libphutil for getting debug output. I wasn't looking to make submittable changes however and managed to get past the need for it (by ignoring it?). As for the lint I believe these projects specify in the .arclint at the root of the project that the linter needs to run when creating a diff.
